Description

  The present invention relates to a system for classifying and displaying information items such as document files, and more particularly to an information classification and display system based on tag data assigned to information items.

  As a method for organizing and managing information such as a large number of document files and image files, there is a hierarchical information classification management method that has been widely used in general personal computers for a long time. For example, a “Windows Explorer” application provided by an OS (operating system) such as Windows XP (registered trademark) manufactured by Microsoft Corporation is based on the above information classification management method (hereinafter referred to as Conventional Technology 1). .

  FIG. 13 shows an example of the operation screen of prior art 1. In this example, “Desktop” is positioned at the highest level, and there are four classification folders “My Document”, “My Computer”, “My Network”, and “Recycle Bin” at the lower level. In addition, each classification folder can hold subfolders in multiple layers in lower layers. For example, there is a “photo” folder in one of the lower layers of “My Document”, and a “2007-ski” folder in one of the lower layers. Under the “2007-ski” folder, five photo files “P0101.jpg”, “P0102.jpg”, “P0103.jpg”, “P0104.jpg”, and “P0105.jpg” are stored.

  This hierarchical information classification management method is an organizing method that gradually refines the classification granularity of information from the upper hierarchy to the lower hierarchy, and has features that are intuitively easy to understand when operated by the user. Generally used widely.

  However, this information classification management method has a problem that one piece of information (such as a document file or an image file) can be stored only in one of the folders of each hierarchy developed in a tree shape. It was difficult to classify information from various viewpoints.

  Under these circumstances, there is a classification method by tagging as an information classification management method that has been rapidly spreading in recent years in image file sharing services and bookmark sharing services on the Internet (hereinafter referred to as Prior Art 2).

  This method is a management method capable of assigning one or more classification information called tag data to one piece of information. For example, a plurality of tag data such as “sea”, “family trip”, “fishing”, “boat”, etc. can be given to an image file of one photo, and when searching for information later, It is an information classification management method capable of collectively searching for information to which certain tag data is assigned, and whose use is rapidly expanding in recent years.

  An example of a user operation screen in “del.icio.us” (http://del.icio.us/), which is one of social bookmark services (bookmark sharing services) in which such an information classification management method is adopted Is shown in FIG. In this service, registrants and other users can freely attach arbitrary tag data to bookmarks registered by the user. In the example of FIG. 14, bookmark information to which tag data “popular” is assigned is listed and displayed among bookmarks registered in the del.icio.us service.

  Such a management method is superior in that it enables organization based on a plurality of classification viewpoints for one piece of information, and its use has begun to expand in some services. This is a new management concept for users who are accustomed to the hierarchical information classification management method, and there is a problem that the operation is difficult to understand intuitively.

  For such a problem, Patent Document 1 describes a method of displaying information classified by tag data in a tree format (hereinafter referred to as Conventional Technology 3).

  In Prior Art 3, tag data given to each of a plurality of documents is acquired and classified, and based on the classification result, the tag data is displayed in a tree format, and the tag data corresponds to the tag data at the end of the tree. Displays a view that displays the document title. For example, as shown in FIG. 2, when eight files A to H to which tag data X, Y, and Z are assigned are classified and displayed by the method according to the conventional technique 3, the result is as shown in FIG. As described above, in the related art 3, when a plurality of tag data is assigned to one file like the files E to H, the same file is displayed repeatedly under each tag data.

  On the other hand, as another technique for displaying data by hierarchically displaying attribute values assigned to data, there is a technique described in Patent Document 2 (hereinafter referred to as Conventional Technique 4).

  In the prior art 4, based on the attribute value assigned to each data and the ranking among a plurality of attribute items, each data is classified by the attribute value, the attribute value is hierarchically configured and the data is displayed. Create and display on the screen of the display device. For example, as shown in FIG. 2, when the eight files A to H to which tag data X, Y, and Z are assigned are classified and displayed by the method of the prior art 4, the order of the tag data X, Y, and Z is first set. Decide. For example, when the tag data X is determined as the first rank, the tag data Y is determined as the second rank, and the tag data Z is determined as the third rank, the hierarchical classification diagram according to the conventional technique 4 is as shown in FIG. As described above, in the prior art 4, each data can be displayed hierarchically according to the order of the designated tag data, and if the order of the tag data is changed, another hierarchical classification diagram in which the way of hierarchization is changed is created and displayed. be able to.

International Publication WO2004 / 111877 Publication Japanese Unexamined Patent Publication No. 2000-250798

  However, in the one-level classification diagram as shown in FIG. 15, it is not easy to find a target information item because it is not possible to narrow down by a plurality of tag data attached to the information item. For example, since the file H has three tag data of X, Y, and Z, the file H exists under the X folder, the Y folder, and the Z folder. Since the files to which only Y and Z are assigned are also displayed together, it becomes difficult to search for a desired file H as the number of files increases.

  On the other hand, according to the hierarchical classification diagram as shown in FIG. 16, it is easy to find a desired information item as long as the rank of the tag data can be appropriately specified. For example, in the case of FIG. 16, it is easy to search for the file B having only the tag data X, the file E having the tag data X and Y, and the file H having the tag data X, Y, Z. However, since the files A, C, D, G, and F are collectively stored in other folders, it is not possible to narrow down by the tag data assigned to them. If you change the order of tag data and create another hierarchical classification chart, the situation may change, but it is wasteful in time and effort to display several hierarchical classification charts in order There are many.

  The present invention has been proposed in view of such circumstances, and its purpose is to display information classification based on tag information that can be effectively narrowed down hierarchically in any order of a plurality of tag data assigned to information items. To provide a system.

  The information classification display system based on tag information of the present invention is tree structure data in which the plurality of information items are classified based on tag data assigned to each of the plurality of information items, and the information item includes a plurality of tags. If there is data, create tree structure data that classifies the information items for each of a plurality of nodes that arrive from the root node via a one-to-one route to all combinations of the plurality of tag data sequences A tree structure data generation means that generates icons representing virtual folders corresponding to the nodes of the created tree structure data, and the generated icons are connected according to the parent-child relationship of the nodes in the tree structure data Display control means for creating a figure and displaying it on the screen of the display means.

  According to the present invention, it is possible to display a classification chart that can be effectively narrowed down hierarchically in any order of a plurality of tag data assigned to information items. The reason is that when the information item has a plurality of tag data, each of the plurality of nodes that reach from the root node via a one-to-one route to all combinations of the plurality of tag data sequences This is because a classification diagram according to the tree structure data in which the information items are classified is created and displayed.

  Next, the best mode for carrying out the present invention will be described in detail with reference to the drawings.

“First Embodiment”
Referring to FIG. 1, an information classification display system 100 based on tag information according to a first embodiment of the present invention includes a data processing device 101, a storage device 102, a display device 103, and an input device 104 connected thereto. It consists of.

  The data processing apparatus 101 is constituted by a central processing unit of a computer, for example, and includes a tree structure data generation unit 111 and a display control unit 112 as functional units. These functional means can be realized by a computer and a program constituting the data processing apparatus 101. The program is provided by being recorded on a computer-readable recording medium such as a CD-ROM, read by the computer when the computer is started up, and the like, and by controlling the operation of the computer, the tree structure data generating unit 111 and the display are displayed on the computer. The control means 112 is realized.

  The storage device 102 includes, for example, a computer main storage or auxiliary storage, and includes an information item storage unit 121, a tag data storage unit 122, a tree structure data storage unit 123, and a classification diagram storage unit 124.

  The display device 103 is composed of, for example, a liquid crystal display, and is used for displaying an operation screen and operation results.

  The input device 104 includes, for example, a keyboard and a mouse, and is used for inputting instructions and data.

  The information item storage unit 121 is an area for storing information items that are target information to be classified and managed, such as document files and image files. Each information item is given a unique identifier such as a file name.

  The tag data storage unit 122 is an area for storing tag data attached to the information item. Referring to FIG. 2, the tag data storage unit 122 stores tag data assigned to a total of eight information items of files A to H, for example. Since the content of the information item itself is stored in the information item storage unit 121, the tag data storage unit 122 records a set of an ID for uniquely identifying the information item and tag data assigned to the information item. ing. In the example of FIG. 2, tag data “X” is assigned to the file B, tag data “Y” is assigned to the file C, and tag data “Z” is assigned to the file D. Each tag data X, Y, Z is an arbitrary character string given by the user for classification. For example, tag data X is “flower”, tag data Y is “sea”, and tag data Z is “summer”. Etc. The number of tag data to be assigned to each information item is arbitrary, and it may be assigned only one as shown in files B to D, or two or more tag data may be assigned as in files E to H. May be. In addition, there may be an information item to which no tag data is assigned, such as file A.

  The tree structure data generation unit 111 is a unit that reads tag data attached to an information item from the tag data storage unit 122 and generates tree structure data in which a plurality of information items are classified. In general, a tree structure is expressed by nodes (nodes) and links (sides) connecting the nodes, and a node at the apex of the tree structure is called a root node. Since the route from the root node to the other node following the link is always uniquely determined, it is generally used as a data structure for classifying information. The tree structure data generation unit 111 according to the present embodiment generates tree structure data for classifying information items according to tag data by associating one tag data with each node or each link. In that case, when a certain information item has a plurality of tag data, each of the plurality of nodes that reach from the root node via a route corresponding to all the combinations of the plurality of tag data in a one-to-one manner Then, tree structure data in which the information items are classified is created.

  The tree structure data created by the tree structure data generation unit 111 is composed of data for each node. In the case of the present invention, each node is treated as if it were a folder in hierarchical information management, so the data for each node is called virtual folder data.

  Referring to FIG. 3, the virtual folder data includes a processing target information item list 211, tag data 212, a folder direct display information item list 213, and a subfolder list 214.

  The processing target information item list 211 is a list of information items that include the virtual folder (node) and are classified into lower layers.

  Tag data 212 is tag data associated with the virtual folder. It does not include tag data assigned to lower layers.

  The display information item list 213 directly under the folder is a list of information items classified directly under the virtual folder. Information items classified in the lower hierarchy of the virtual folder are not included.

  The subfolder list 214 is a list of other virtual folders connected immediately below the virtual folder.

  The tree structure data storage unit 123 is a storage area for storing the tree structure data generated by the tree structure data generation unit 111.

  The display control unit 112 is a unit that reads out the tree structure data from the tree structure data storage unit 123, creates a classification diagram in which the information items are classified according to the tag data, and displays it on the screen of the display device 103. In the case of the present embodiment, the display control unit 112 includes a classification diagram generation unit 113 and a display processing unit 114.

  The classification diagram generation means 113 is a means for generating an icon representing a virtual folder corresponding to each node of the tree structure data, and creating a classification diagram in which the generated icons are connected according to the parent-child relationship of the nodes in the tree structure data. is there.

  The display processing unit 114 displays the classification diagram generated by the classification diagram generation unit 113 on the screen of the display device 103, reads the information item selected on the classification diagram from the information item storage unit 121, and displays the classification information on the display device 103. It is a means to perform the process displayed on this screen.

  The classification diagram storage unit 124 is an area for storing the classification diagram generated by the classification diagram generation unit 113.

  Next, the operation of the information classification display system 100 based on tag information according to the present embodiment will be described.

  When the user wants to perform information classification display based on the tag information, the user inputs an instruction to that effect from the input device 104. At this time, if there are a plurality of tag data storage units 122, the tag data storage unit 122 to be processed is selected by a parameter.

  When the information classification display instruction based on the tag information is input from the input device 104, the data processing apparatus 101 starts the tree structure data generation process shown in FIG.

  Referring to FIG. 4, the tree structure data generation unit 111 first creates a root folder for displaying all display target information items hierarchically (step S101). Specifically, the processing target information item list 211, the tag data 212, the folder display information item list 213, and the subfolder list 214 in FIG. 3 are all stored in the tree structure data storage unit 123 for the root folder initialized by NULL. Generate virtual folder data.

  Next, the tree structure data generation unit 111 adds all information item IDs stored in the tag data storage unit 122 to the processing target information item list 211 of the root folder (step S102). For example, in the case of the tag data storage unit 122 in FIG. 2, IDs of eight information items of the files A to H are added.

  Next, the tree structure data generation unit 111 calls and executes a folder processing procedure for the root folder created in step S101 (step S103).

  Next, details of the folder processing procedure will be described with reference to the flowchart of FIG.

  In the folder processing procedure, the tree structure data generation unit 111 first sets one processing target information item (information item (i)) from the processing target information item list 211 of the processing target folder (folder (f)). ) (Step S201).

  If there are no more processing target information items (Yes in step S202), the process proceeds to step S220.

  When one processing target information item is acquired (No in step S202), the tree structure data generation unit 111 acquires one tag data not included in the tag data 212 of the folder (f) from the tag data of the information item. (Step S203). If such tag data cannot be acquired in step S203 (Yes in step S204), the tree structure data generation unit 111 adds the information item (i) to the display information item list 213 directly under the folder (f) (step S204). S205) Returning to step S201, the next processing target information item is acquired.

  When tag data can be acquired in step S203 (assumed to be tag (t)), the tree structure data generation unit 111 checks whether or not the tag (t) is included in the subfolder list 214 of the folder (f). (Step S207).

  When the tag (t) is included in the subfolder list 214 of the folder (f) (No in step S207), the process proceeds to step S210.

  On the other hand, if the tag (t) is not included in the subfolder list 214 of the folder (f) (Yes in step S207), the tree structure data generating unit 111 adds the tag (t) to the subfolder list 214 of the folder (f). It adds (step S208). Next, the initialized virtual folder for the added tag (t) is generated in the tree structure data storage unit 123, and the tag data 212, the tag (t) of the folder (f) Is added (step S209). Then, the process proceeds to step S210.

  In step S210, the tree structure data generation unit 111 adds the information item (i) to the processing target information item list 211 of the subfolder corresponding to the tag (t) (step S210).

  Next, the tree structure data generation unit 111 acquires one next tag that is not included in the tag data 212 of the folder (f) from the tag data of the information item (i) again (step S211). If such tag data cannot be acquired in step S211 (Yes in step S212), the process returns to step S201 to acquire the next processing target information item. If tag data can be acquired in step S203, the process returns to step S206, and the processes in and after step S206 are repeated.

  In step S220, the tree structure data generation unit 111 acquires the subfolder list 214 of the folder (f).

  Next, one subfolder is acquired from the subfolder list 214 (step S221). Let the acquired subfolder be a subfolder (f ').

  At this time, if the subfolder (f ′) cannot be acquired (Yes in step S222), the folder process is terminated (step S224). If the subfolder (f ′) is acquired (No in step S222), the acquired subfolder (f ′) is Folder processing is performed recursively (step S223).

  After completing the process in step S223, the process returns to step S221 to acquire one next subfolder, and the processes in and after step S222 are repeated.

  FIG. 6 shows an example of tree structure data generated by the tree structure data generation unit 111 with the tag data storage unit 122 of FIG. In FIG. 6, R is a root folder, R-X, R-Y, and R-Z are subfolders immediately under the root folder, R-X-Y and R-X-Z are subfolders immediately under the sub-folder R-X, and R-Y. -X, R-Y-Z are subfolders immediately under subfolder RY, RZ-X, RZ-Y are subfolders immediately under subfolder RZ, and RXYZ is subfolder R-X-. Subfolder immediately under Y, RXXZY is a subfolder immediately under subfolder RXZ, RYXZ is a subfolder immediately under subfolder RY-X, and RYZX is a subfolder A subfolder immediately under RYZ, RZXXY is a subfolder immediately under subfolder RZ-X, and RZYX is a subfolder immediately under subfolder RZ-Y. The first line is the processing pair Information item list 211, row 212,3 row tag data is 213,4 row folder directly below the display information item list shows the contents of a subfolder list 214.

  In the tree structure data of FIG. 6, when a certain information item has a plurality of tag data, all combinations of the plurality of tag data are reached from the root folder R via a one-to-one route. The information item is classified into each of the plurality of subfolders. For example, the information item H has three tag data of X, Y, and Z, and all combinations of the tag data array are 1) XYZ, 2) XZY, 3 6) Y-X-Z, 4) Y-Z-X, 5) Z-X-Y, 6) Z-Y-X, and reach from the root folder R via the corresponding paths. Of subfolders R-X-Y-Z, R-X-Z-Y, R-Y-X-Z, R-Y-Z-X, R-Z-X-Y, R-Z-Y-X The information item H is described in the information item list 213 displayed directly under each folder.

  When the data processing apparatus 101 completes the generation of the tree structure data by the tree structure data generation unit 111, the data processing apparatus 101 then starts the display control process by the display control unit 112.

  First, the classification diagram generation unit 113 of the display control unit 112 reads out the tree structure data from the tree structure data storage unit 123, and generates an icon representing a virtual folder corresponding to the root folder and each subfolder together with a folder name to be displayed on the icon. To do. As the folder name, for example, the character string “root folder” is used in the case of the root folder, and in the case of each subfolder, for example, tag data corresponding to the subfolder (described in the tag data 212 of the subfolder). Tag data obtained by removing tag data described in the tag data 212 of a higher-order subfolder from one or more tag data.

  Next, the classification diagram generation unit 113 connects icons representing virtual folders corresponding to the root folder and each subfolder with line segments according to the parent-child relationship of the nodes indicated by the subfolder list 214 of each folder in the tree structure data. Information to be generated. Also, an icon corresponding to the information item described in the display information item list 213 directly under the folder of each subfolder is generated together with the information item name to be displayed, and information connected to the icon corresponding to the subfolder by a line segment is generated. To do. As the information item name displayed on the information item icon, for example, the ID of the information item described in the display information item list 213 directly under the folder of the subfolder is used. Finally, all these pieces of information are temporarily stored in the classification diagram storage unit 124 as classification diagram data.

  Next, the display processing unit 114 of the display control unit 112 reads out the classification diagram data from the classification diagram storage unit 124, and displays the classification diagram expressed by the classification diagram data on the screen of the display device 103.

  An example of a classification diagram displayed on the screen of the display device 103 based on the classification diagram data generated from the tree structure data of FIG. 6 is shown in FIG. Referring to FIG. 7, three folders of tag X, tag Y, and tag Z and a file A that is an information item without a tag are displayed as virtual folders immediately below the root folder.

  Further, under the tag X folder, two folders of a tag Y and a tag Z and a file B to which only the tag X is assigned are displayed. Further, under the tag Y folder under the tag X folder, the tag Z folder and the file E to which the tag X and the tag Y are assigned are displayed, and the tag Z folder under the tag Y folder under the tag X folder. A file H to which a tag X, a tag Y, and a tag Z are assigned is displayed below. Further, under the tag Z folder under the tag X folder, the tag Y folder and the file F to which the tag X and the tag Z are attached are displayed, and the tag Y folder under the tag Z folder under the tag X folder. A file H to which a tag X, a tag Y, and a tag Z are assigned is displayed below.

  Under the tag Y folder and the tag Z folder, the same hierarchical display as that under the tag X folder is also made.

  When the icon of any information item displayed in the classification diagram as shown in FIG. 7 is clicked by the mouse operation of the input device 104, the display processing means 114 of the display control means 112 is displayed on the clicked icon. The information item storage unit 121 is searched using the information item name as a key, and the acquired information item is displayed on the display device 103. This allows the user to display the contents of any information item on the screen.

  Here, the classification diagram shown in FIG. 7 displays the classification information based on the tag data with the classification granularity gradually reduced from the upper hierarchy to the lower hierarchy, and the folder in the conventional hierarchical information management. Similar to. For this reason, even a user who is accustomed to the conventional hierarchical information management method can handle the information without discomfort.

  In addition, information items having a plurality of tag data are classified into a plurality of folders that arrive from the root folder via a route corresponding to one-to-one correspondence with all combinations of the plurality of tag data. Therefore, it is possible to easily find an information item using the tag data as a key. The reason for this is, for example, in the case of file H, whether the search from the root folder is performed by tag X → tag Y → tag Z, tag Y → tag Z → tag X, or any other order. This is because the target file H can be reached even when searching.

  The classification diagram shown in FIG. 7 displays all hierarchies based on tag data. However, the present invention is not limited to the display of the classification diagram in a format that gives an overall overview of the entire hierarchical structure, and it is also possible to use a classification diagram that is displayed in hierarchical units. An example is shown in FIG.

  In the example shown in FIG. 8, the display processing unit 114 initially displays only the root folder on the screen of the display device 103 as shown in (A), and when the focus is given to the root folder, as shown in (B). Switch to the screen that displays the virtual folders and files directly under the root folder. Further, when the focus is given to the folder of the tag X, as shown in (C), the screen is switched to a screen for displaying the virtual folder and the file immediately below the tag X, and when the focus is given to the folder of the tag Y there, The screen is switched to a screen for displaying virtual folders and files directly under Y, and finally reaches a screen where no subfolder exists as shown in (E).

  In addition, the display processing unit 114 displays the classification diagram selected by the user through the input device 104 out of the classification diagram of the format shown in FIG. 7 and the classification diagram of the format shown in FIG. May be. An example of the screen of the display device 103 in that case is shown in FIG.

  Referring to FIG. 9, two buttons named “Overall view” and “Individual folder view” are arranged at the upper part of the screen of the display device 103. In the state, a classification diagram of the format shown in FIG. 7 is displayed at the bottom of the screen. In the state (B) in which the button of the individual folder view is turned ON, a folder hierarchy diagram is displayed on the left side of the lower portion of the screen, and the classification of the format shown in FIG. The figure is displayed on the right side.

“Second Embodiment”
Referring to FIG. 10, the information classification display system 300 based on tag information according to the second embodiment of the present invention has a data processing device 101 that is compared with the first embodiment shown in FIG. In addition to the tree structure data generation unit 111 and the display control unit 112, the difference is that a classification information adding unit 311 is further provided.

  The classification information adding unit 311 is configured to display a folder when an operation for adding a certain information item is performed to any folder in the classification diagram of FIG. 7 or 8 displayed on the screen of the display device 103. This is a means for performing processing for assigning the tag data 212 to the information item. An example of the processing is shown in FIG.

  Referring to FIG. 11, when an operation of adding an arbitrary information item to any folder in the classification diagram displayed on the display device 103 is performed (step S301), the classification information adding unit 311 Is acquired from the tree structure data storage unit 123 (step S302), and the acquired tag data is added to the tag attribute of the information item (step S303).

  For example, as shown in FIG. 12, the classification diagram of the state of FIG. 8B is displayed on a part of the screen of the display device 103, and the icon of the file I displayed at another part of the screen is set as a tag X. When the user drags and drops the folder, the classification information adding unit 311 determines that an operation for adding the file I to the folder of the tag X has been performed (step S301). Next, the classification information giving unit 311 reads the folder of the tag X from the tree structure data storage unit 123 and acquires the tag data X described in the tag data 212 (step S302). Next, the classification information adding unit 311 searches the tag data storage unit 122 using the ID of the file I as a key, and if the information item having the same ID is not registered, the ID acquired in the step S302. A set with data is added to the tag data storage unit 122 (S303). If an information item having the same ID has already been registered, the tag data stored corresponding to the ID is rewritten with the tag data acquired in step S302.

  In conjunction with the update of the tag data storage unit 122 by the classification information adding unit 311, the tree structure data generation unit 111 may recreate the tree structure data and the display control unit 112 may redisplay the classification diagram. good.

  Operations other than the classification information providing unit 311 are the same as those in the first embodiment.

  As described above, according to the present embodiment, one or more tag data can be simultaneously given to an information item by an intuitively easy-to-understand operation such as drag and drop of the information item to the file in the classification diagram.

  The present invention can be applied to a display system for searching for tagged information in a document management system and a display interface for online albums such as photos and images. Further, the present invention can also be applied to an information presentation interface in a service in which a plurality of users share information on a network such as a bookmark sharing service, an image sharing service, and a file sharing service.
